Episode ES-SUB-12-300-MB Powered Subwoofer Reviewed


Episode has released their largest subwoofer to date with the ES-SUB-12. While its looks may not be so impressive, reviewer Andrew Robinson's evaluation claims the performance is quite the opposite.

The ES-SUB-12's build quality is phenomenal, possessing smooth lines, solid construction and the warranty to back it up. While the finish may not be automotive grade, it's not supposed to be, for the ES-SUB-12 is designed with the intention of being...

The ES-SUB-12's grille is a bit finicky and cheap, but then again, you'd probably leave it off when installing it into an AV cabinet anyway ; I'm sure many will criticize the ES-SUB-12 for its simplicity, for many subs in its price bracket feature some...

To say that I was impressed following my time spent with Episode's big daddy subwoofer, the ES-SUB-12, is a bit of an understatement. At first glance, there's little to get excited about, for the ES-SUB-12 appears to be behind the times in terms of...

Klipsch Synergy


Read our review to find out what the best bookshelf speaker available is. The Klipsch B-20 is sure to surprise you.

These speakers are highly efficient. They are powerful but don’t waste any energy

The lowest frequency these speakers can produce is 62Hz

The Klipsch B-20 speakers are the best speakers we reviewed. They would make a versatile and dynamic addition to your stereo system or home theater.

Klipsch Synergy B-10


Great highs, good mids

Some guy gave them 2 stars and said dissapointing cause he was comparing them to Bowers and Wilkins 685's.....LOL......some people just aren't born with it ; These are seventy dollar bookshelf speakers, not Bowers and Wilkins 685's

Well reinforced cabinets, nice look, good size, nice binding posts

Based on the build quality, heft, appearance (both aesthetic and functional), brand and specs, I was almost ready to place a second order before I'd even finished hooking up the first pair I had received ; Unfortunately the sound was disappointing. My...

Great office speakers


I have these powered by an SMSL SA-36A amp. Sounds much better than a pair of $100 speakers and a $52 amp have a right to. If I had it to do over again I would have sprung the $16 extra for the higher powered SMSL SA-50 as the B-10s can take everything...

I was looking for something with more hi-fi sound for my office than my 2.1 computer speakers (which were already pretty good). These B-10s definitely hit the mark. Acoustic guitar, piano and vocals sound like they're right there in front of me. It's...

The bass in these isn't huge, but it's there. If you want to shake the walls you shouldn't be looking at compact bookshelf speakers ; These speakers have no audiophile cred on the Internet. Even the Klipsch website shows them as discontinued....

Great Sound For Such A Small Speaker


If these speakers are available in another color, that would he helpful. Most people use a wood grain color or walnut.

Small size. Great clear sound. I have these speakers wired to an old JVC R-K22 and they sound magical. I would recommend them to anyone trying to find small speakers that are out of the way and sound great

Maybe I'm a cheapskate but I think all speakers should come with wires

not bad for the price


There are many arguments online on how this sub should be placed, just trust your ears and put it where it sounds best from your listening location.

For the price, it really has some punch and clarity

It's discontinued now

Best value on the market.

Great price, free shipping! I have the sub set to about 40% of what it is capable of and it still rocks the house. Very easy to adjust into my setup. Did not have any problems with shipping. Plug and play right out of the box

Now I want to upgrade the rest of my speakers

Product Specifications

The Synergy Series Sub-12 hurls out enough power and bass extension to shake the foundation. It uses high-quality materials and the most reliable components to create a rock-solid impact that makes your movies and music come alive. The Sub-12 gets its intensity from a 12-inch, down-firing driver coupled to a highly efficient BASH Class D amplifier that creates 300 watts of continuous power and 650 watts of dynamic power. Because of its ample enclosure size and large, rear-firing port with flared ends, the Sub-12 produces increased bass response with low distortion. The subwoofer's built-in, steep-slope (24dB/octave) low-pass crossover is continuously adjustable from 40 to 120Hz. A phase control facilitates acoustical integration of the subwoofer with the other speakers in the system. An "auto power" feature enables the subwoofer to turn itself on and off (standby) automatically, based on the presence or absence of an audio signal. A blue/red dual color LED display on the front of the subwoofer indicates whether the unit is on or in standby mode. In addition to its ability to play louder and go deeper than anything else in its class, the Sub-12 features a new industrial design that is refined and aggressive. Available in a black finish with titanium accents, this extraordinary subwoofer matches the entire Synergy Series lineup in both style and performance. Because it wraps technical superiority and eye-catching cosmetics into one affordable package, the Sub-12 perfectly anchors a home theater or two-channel system.
